P.44 Assume the following simplified dependence of the
pressure in a ventricle of the human heart as a function of the
volume of blood pumped.

Ps, the systolic pressure, is 120. mm Hg, corresponding to
0.158 atm. Pa, the diastolic pressure, is 80.0 mm Hg, corre-
sponding to 0.105 atm. If the volume of blood pumped in one
heartbeat is 75.0 cm³, calculate the work done in a heartbeat.
